When your doing your girlfriend in the ass and just before you come you smack her in the head with a shovel, not too hard as you don't want to knock her out. At which point she should turn and you pull out and come in her eye. Then hand her the shovel and push her backwards onto a chair, holding her bruised head and squinting at you with a shovel in her hand, she will now remind you of an angry gravekeeper.

Gus: hey jack, I heard you gave Meg the angry gravekeeper last night.
Jack: yeah... she was pissed. I thought she was gonna hit me with the shovel.
